buy button greyed out

A similar issue was reported yesterday:

Not able to sell anything - button greyed out

I am not able to sell anything in my portfolio. No problem buying. The sell button is greyed out. Every position in my portfolio has this issue. I can tap on the buy button and buy more but the sell button is greyed out and I am not able to sell. Logging out and back in also does not make a difference. What’s going on here?
